| Summary: | In the last decade, the use of implants in spinal surgery has significantly increased, particularly interbody devices and transpedicular fixators. This trend has necessitated refining approaches aimed at preventing intra- and postoperative complications. A key factor influencing the effectiveness of stabilization procedures is bone mineral density (BMD).
Objective: To investigate the relationship among vitamin D levels, BMD, and the incidence of implant-related failures in patients who have undergone stabilization procedures on the spine, as well as to evaluate the role of postoperative correction of vitamin D₃ and K2 deficiencies in enhancing fixation stability and reducing complication risks.
Materials and Methods: A retrospective single-center cohort study was conducted in specialized departments of Romodanov Neurosurgery Institute NAMS of Ukraine, from January 2023 to December 2024. A total of 250 patients who underwent spinal surgery with the use of transpedicular screws and/or interbody implants were analyzed with respect to their age, sex, body mass index, serum vitamin D (25-(OH)D₃) levels, and BMD (according to computed tomography data). Original grading scales were used to evaluate implant-related complications. Postoperative correction of vitamin D deficiency was carried out using “Solemax®” (vitamin D₃, vitamin K2, and ω-3 polyunsaturated fatty acids).
Results: A high prevalence of vitamin D deficiency and reduced BMD was recorded among patients undergoing elective stabilization surgeries on the spine. A significant correlation was detected between 25-(OH)D₃ levels and bone tissue status. After 4 months of “Solemax®” administration, all patients achieved reference 25-(OH)D3 levels, indicating the effectiveness of the therapy. In the correction group, an increase in BMD was observed, whereas in the comparison group, BMD values decreased. The incidence of implant-related complications was statistically reduced: the risk of screw loosening decreased by 69.84% over the first 6 months and by 85.06% over one year, while the risk of interbody implant migration declined by 56.2% and 64.7%, respectively.
Conclusions: The stability of spinal fusion is more contingent upon the adaptive response of bone tissue to implantation than on absolute BMD values. The use of a balanced combination of vitamins D₃ and K2 contributes to enhanced fixation stability and a lower risk of postoperative complications. |
